Hi!I'm using an old ZCS 6. I'm migrating it to a newer version but it take time...I'm trying to implement SSL/TLS on imap and smtp connections on the current system, so i've issued a new certificate (with wildcard *.domain.com) via the admin web console.I've installed the certificate in the Trusted Root Certification Authorities Certificate Store at the clients, but i still get an error when outlook connects to the server. Looking at the certificate is missing the issuer so that the certificate can't be verified.How i can fix this? I need to creade a self signed certificate with correct issuer and deploy it to the clients?Really thanks!

The error that i get is "A certificate chain processed, but terminated in a root certificate which is not trusted by the trust provider". In windows normally you can fix this installing the root certificate of the server in the local Trusted Root Certification Authorities Certificate Store, so that the certificate can be trusted. If i open the certificate i get a warning about missing the issuer.there isn't a way to fix this using simply self signed? The root certificate is easly deployed by GPO....Really thanks for the help...

You can search this forum about this issue. You can install root cert on windows for old outlook version. However, from outlook 2010, as i remember, you have to use "commercial" one (and letsencrypt, etc).Regards.
